MINERS LAMP.

SPECIFICATION forming part of Letters Patent No. 431,734, dated July 8,1890.

Application filed. January 24, 1890. Serial No. 337,975. (No model.)

the invention, which will enable others skilled in the art to which itappertains to make and use the same,reference being had to the accompanying drawings, which form a part of this specification.

W'hen made of sheet metal, these lamps have heretofore been constructedwith their bodies and bottoms formed separate and connected by asoldered joint; but the rough usage to which these articles are exposedfrequently causes an opening at this joint, which causes the lamp toleak, to the discomfort of the miner. To remove the wick or draw itfarther out of the wick-tube, the miner inverts the lamp, and, graspingthe hook at its rear side, strikes the front edge of the bottom sharplyon the edge or corner of any suitable object. This action jars the wickout of the tube, but at the same time is liable to, and does eventually,separate the bottom from the body.

' The joint at the bottom of the lamp is usually formed by bending theperiphery or edge of the bottom up against the outer surface of thebody, thereby forming a projecting flange or rib, which serves to enablethe miner to strike a firm blow, and thereby quickly and effectually jarthe wick into the desired position. It is desirable, therefore, toprovide lamps with this projecting flange or rib, as it is of advantageto the miner; but it will be readily seen that when said flange or ribis formed by the joint between the body and the bottom of the lamp anopening is soon effect-ed and the lamp is rendered useless.

The object of my invention is to provide a lamp which has the advantageof the abovementioned flange or rib, but is not open to thedisadvantages referred to in connection therewith, and this object Iattain by forming the bottom andbodyof the lamp from a single sheet ofmetal by drawing, stamping, or pressing.

In the accompanying drawings is illustrated a lamp made in accordancewith my invention, in which- Figure 1 is a side view thereof. Fig. 2 isa vertical central sectional view of the same, and Fig. 3 is a side viewof a lamp the body of which has a-slightly difierent form.

The body A of the improved lamp may be formed integral with the bottom13 thereof by means of a draw-press, which will produce the desired formfrom a single flat sheet of metal. Around the periphery of the saidbottom, at the junction of the latter with the side or body of thela1np,is a rounded rib O, which projects out slightly beyond the surfaceof the body and performs the same function as the corresponding flangeor rib which has been referred to in connection with the ordinary formsof lamps, in which the body and bottom are formed from separate pieces,with a joint at .the an glenamely, this flange or rib 0 enables theminer to jar the wick out of the wicktube by striking the same on aprojecting edge or corner of any suitable object. In this improved forrhof lamp, however, the objection heretofore urged in connection with theordinary form of lamps is overcomenamely, the separation from the bodyof the bottom. It will be seen that this cannot result from blows struckon this projecting flange or rib, because there is no joint. Thus Istill retain the advantages of the flange or rib in my improved lamp,and at the same time overcome the disadvantages connected therewith byforming the body and bottom integral by drawing, stamping, or pressing,and forming said flange or rib integral with the body and bottom by thesame operation. The wick-tube is also preferably drawn in the samemanner as the body of the lamp, and thereby formed without the joint,which usually extends from one end thereof to the other. In the ordinaryforms of lamps this wick-tube is provided with a soldered joint, whichis liable to be opened by the melting of the solder.

In Fig. 3 I show a different shape of lampbody; but it will beunderstood that any preferred form of body may be produced by the sameprocess as described namely, drawing.

I am aware that heretofore various utensils and articles have beenformed with their sides and bottom integral by casting; but I havedemonstrated to mysatisfaction that this manner of constructing minerslamps is impracticable from the very obvious fact that the castingcannot be made thin enough to form a lamp which will be light enough tocarry upon the hat. The metal will not flow thin enough to form a lampwhich can be carried in this way. Furthermore, I am aware that variousarticles have been formed from drawn metal, with their sides and bottomintegral; but I do not claim this, broadly. I do not desire to claim themethod of constructing vessels with their sides and bottom integral,consisting in drawing, stamping, or pressing, for I am well aware thatthis is not new; but from the foregoing description it will be readilyunderstood that my invention consists solely in constructing a minerslamp in a peculiar way, whereby the joint at the bottom is dispensedwith without dispensing with the very necessary and useful flange orrib. This manner of forming the lamp with a rounded flange or rib,which, obviously, is hollow, dispenses with all angles, and thereforeprevents the accumulation of dirt and enables the lamp to be readilycleaned.

Itwill be understood that my improved lamp may be made of any suitablesheet metal-as brass, copper, tin, &c.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

A miners lamp formed from a single sheet of metal by drawing, pressing,or stamping,
